I was trying to install a Python package but showed an error as below, I think it might be because I used my company's laptop and it got censored, but I am not sure whether that is the reason, if there are any other possible solutions please help. Python 3.7 pip 10.0.1

(base) C:\>pip install pyvis
Collecting pyvis

  • hi @CForce99, thanks for the answer, after I typed first command, it is showing:tensorboard 2.3.0 has requirement setuptools>=41.0.0, but you'll have setuptools 40.2.0 which is incompatible. google-auth 1.22.0 has requirement setuptools>=40.3.0, but you'll have setuptools 40.2.0 which is incompatible.

Based on your comments try: pip install --upgrade setuptools

Then try retry: pip install pyvis

  • Your answer does not answer the ssl error, the right way to add to an answer is to edit the orignal one.

  • For what I know, the ssl error might be caused by pypi rejecting the older version, but you may very well be right.

  • You are right but he can't update setuptools becuase of the ssl error.

  • Then I think the solution may be to download the files from the setuptools pypi repo and use then manually
